ASUS P5B wifi AP under vista help!!!!

We've just bought the Asus P5B wifi ap-deluxe and installed vista as OS.
But... we have trouvle getting on the wireless network!

The wireless network is being recognized, but somehow we can't connect!
Any idea what the reason can be? The troubleshooter of the computer has no idea what might cause it!

oh yes, I have used the correct WEP encription

Turn off any security, it only adds to the confusion of trying to debug a problem.

Check that your client is getting a valid IP, that is assuming you can connect to the AP in the first place.

If you client can't even connect then there is probably a configuration issue, most likely with the client but this is purely speculative.

If you client can connect and has a valid IP then double check the IP values to ensure everything is pointing to where it is ment to be.
